How one landlord saved £280,000 remortgaging 77 buy-to-let properties with Paragon

£280,000 saved across a 77-property buy-to-let remortgage

For professional landlords with large portfolios, the choice of lender can make a six-figure difference to the overall cost of refinancing.

Paragon Bank recently helped a portfolio landlord remortgage 77 buy-to-let properties, achieving savings of approximately £280,000 by utilising Paragon Bank's innovative Multi-Property Proposition (MPP).

The case highlights how specialist buy-to-let lenders are evolving to meet the needs of professional landlords and why understanding the differences between lenders can have a major impact on costs, administration and long-term portfolio management.

The buy-to-let portfolio remortgage challenge

The client owned 77 buy-to-let properties and was looking to refinance their portfolio efficiently while reducing borrowing costs and simplifying the process. Traditionally, refinancing a portfolio of this size can create significant expenses including multiple mortgage applications, numerous legal processes, repeated valuation and administration costs, Independent Legal Advice (ILA) requirements for each property and arrangement fees charged on every mortgage application.

For landlords transferring properties from personal ownership into a limited company structure, these costs can quickly escalate further.

The solution: Paragon's multi-property proposition

Paragon's Multi-Property Proposition allows landlords to include between 4 and 99 properties within a single application. The proposition was designed specifically for growing portfolio landlords looking for a more streamlined approach to borrowing. Paragon assigns a single underwriter to the entire case, providing direct access throughout the application process and reducing delays.

How £280,000 was saved

1. No buy-to-let mortgage application fees

Paragon charged zero application fees across the entire multi-property application.

On large portfolios, avoiding individual application fees can immediately save thousands of pounds. Paragon estimates landlords can save up to £299 per property through its fee-free structure.

It is not unusual for buy-to-let arrangement fees to range between £495 and 3% of the loan amount.

2. Only one independent legal advice certificate

One of the largest savings came from legal costs.

Many portfolio refinancing exercises require Independent Legal Advice (ILA), particularly when borrowing through limited companies and providing personal guarantees.

Rather than requiring separate legal advice certificates for each property, Paragon requires just one ILA certificate for the entire application, dramatically reducing solicitor costs.

3. Lower buy-to-let interest rates

The client secured a more competitive rate than their existing borrowing arrangements, generating significant long-term savings across the portfolio.

Even a small reduction in rate can create substantial savings when applied across dozens of properties and millions of pounds of borrowing.

4. Reduced arrangement fees

Paragon's structure also resulted in lower overall arrangement fees than refinancing individual properties.

Combined with the legal savings, this contributed significantly to the overall £280,000 saving.

Why Paragon stands out for portfolio buy-to-let remortgages

One of the most attractive aspects of Paragon's Multi-Property Proposition is its flexibility.

Landlords can include between 4 and 99 properties in one application, mix different property types, including standard buy-to-lets, HMOs and multi-unit blocks and see the proposition for purchases and remortgages. It is also possible to complete properties at different times and work with a dedicated underwriter throughout the mortgage process, so questions can be answered quickly and efficiently without waiting in a queue. 

However, it is important to understand that although Paragon allows a single application, it generally issues a separate mortgage offer for each property in the portfolio.

How does this compare with Aldermore?

Aldermore has long been recognised as a specialist lender for portfolio landlords and offers its own multi-property mortgage solution.

Unlike Paragon's structure, Aldermore combines multiple properties into a single mortgage account, creating one mortgage account, one direct debit, one maturity date, one blended loan-to-value calculation and one affordability stress test across the portfolio.

Aldermore currently allows up to 30 properties on one multi-property application and is particularly popular with landlords seeking to simplify portfolio management.

Key benefits of Aldermore's multi-property approach

For landlords incorporating properties into a limited company structure, Aldermore can offer significant savings because:

• Personal guarantee charges are applied per application rather than per property

• Independent legal advice costs can be reduced substantially

• Free legal packages are available on some remortgages

• Free valuations are available on standard properties

However, Aldermore's multi-property mortgages generally require all properties to complete on the same day and are limited to portfolios of up to 30 properties per application.

Which lender is better for portfolio landlords?

There is no universal answer.  For landlords refinancing very large portfolios, Paragon's ability to accommodate up to 99 properties in a single application provides a level of scale that few lenders can match. The combination of no application fees, a single ILA requirement and direct access to one underwriter can create substantial savings.

For landlords seeking a truly consolidated mortgage structure with one account and simplified ongoing management, Aldermore's multi-property proposition remains highly attractive.

The right choice depends on the portfolio size, ownership structure, whether properties are held personally or within a limited company, future acquisition plans, refinancing objectives and appetite for administrative simplicity.

Aaron Strutt, product director at Trinity Financial, says: "Aldermore, TML and Paragon are three of the more well-known buy-to-let lenders willing to remortgage large buy-to-let portfolios on single applications. Some will issue multiple mortgage offers once a portfolio remortgage is agreed, while others will issue a single mortgage offer.  The number of applications needed affects the arrangement fees charged and the legal fees, especially if a buy-to-let portfolio is being switched to a limited company structure. This Paragon deal is quite unusual, but clearly the landlord is making big savings." 

Research by The Mortgage Works found that two-thirds of landlords (67 per cent) were unaware that rented homes will require a minimum energy-efficiency rating of C when the regime comes into force in October 2030. Energy performance certificates grade properties on a scale from A to G, with A being the most energy-efficient, and they apply for 10 years. Many landlord may well have to remortgage to release funds to make improvements to their property portfolios. 

Thinking about refinancing a buy-to-let portfolio?

As this recent 77-property remortgage demonstrates, specialist portfolio lending solutions can generate substantial savings when structured correctly.

If you're refinancing multiple buy-to-let properties, considering incorporation into a limited company, or looking to reduce borrowing costs across an existing portfolio, specialist advice can help identify the most suitable lender and potentially save tens—or even hundreds—of thousands of pounds.
